You used to be able to buy them from whiteline here in Australia, but I don't think you can anymore. I have one on my car and so does Hugh, not sure if anyone else ever bought one!
I think your best bet may be to remove it and straighten it out if you can. The stock bar does have a FACTORY 'dint' in the middle of it, where it sort of squishes, so if thats the issue then its there from the factory.
Put up a picture of the damage if you can mate.
